Abstract

With the increasing prevalence of multi-band detection technologies, military equipment and weapons face heightened risks of exposure to enemy detectors, posing significant challenges to stealth capabilities. This paper proposes a multispectral stealth metamaterial (MSM) designed for cross-band stealth applications in laser, infrared, and radar domains. The device integrates a one-dimensional photonic crystal (1D-PC) and a radar-absorbing metamaterial (RAM), achieving a low specular reflectivity (average value of 0.25) across the 8–14 μm range, over 98 % absorption at 10.6 μm, and more than 90 % absorption efficiency within the 7.5–18 GHz radar band, while simultaneously suppressing high emissivity in the infrared band. A 10 × 10 cm2 sample was fabricated and tested, demonstrating the device’s multispectral modulation performance. This work provides a novel approach to multispectral modulation and thermal radiation management, offering potential advancements in stealth technology.

设计和分析一种多光谱兼容的隐身超材料，用于增强激光、红外和雷达光谱波段的隐身能力

随着多波段探测技术的日益普及，军事装备和武器面临着更大的暴露于敌方探测器的风险，给隐身能力带来了巨大挑战。本文提出了一种多光谱隐身超材料（MSM），设计用于激光、红外和雷达领域的跨波段隐身应用。该器件集成了一维光子晶体（1D-PC）和雷达吸收超材料（RAM），在 8-14 μm 范围内实现了较低的镜面反射率（平均值为 0.25），在 10.6 μm 处的吸收率超过 98%，在 7.5-18 GHz 雷达波段内的吸收效率超过 90%，同时抑制了红外波段的高发射率。制作并测试了一个 10 × 10 平方厘米的样品，证明了该器件的多光谱调制性能。这项工作为多光谱调制和热辐射管理提供了一种新方法，为隐形技术的发展提供了可能。
